hey im all new to root beer. i am a successful home beer brewer and the new hype is hard root beer. is there anyone out there making it?. do you have any tips and tricks i need to know?

my thoughts

brew a normal batch of root beer
pitch champagne yeast and let ferment
heat fermented root beer to kill the yest but not to hot to evaporate the alcohol
add some sugar to your desired sweetness level
put in keg and force carbonate at around 23psi??
